Which one of the following is not correctly matched?

An organic compound $(X)$ with molecular formula $C_3H_6O$ is not readily oxidised. On reduction it gives $(C_3H_8O)$ $(Y)$ which reacts with $HBr$ to give a bromide $(Z)$ which is converted to a Grignard reagent. This Grignard reagent on reaction with $(X)$ followed by hydrolysis gives $2,3-$dimethylbutan$-2-$ol. Compounds $(X)$,$(Y)$ and $(Z)$ respectively are $:$

The following reagent converts $C_6H_5COCHO$ to $C_6H_5CHOHCOONa$.

Identify the compound $A$ in the following reaction: $A + CH_3MgBr$ $\xrightarrow{\text{dry ether}} \text{intermediate}$ $\xrightarrow{H_3O^+} CH_3CH_2OH + Mg(Br)(OH)$
